Objetivo

El objetivo general del curso es dotar a los asistentes de lahabilidad bsica del uso de la herramienta MATLAB, como unsoftware de computo tcnico. Al final el curso, los asistentes

podrn realizar las 3 tareas bsicas del computo tcnico:Obtener datos de diversos medios; Procesarlos matemticamentey visualizarlos; Compartir los resultados a travs de aplicacionesy reportes .

Principales Beneficios

MATLAB es un software lder en el computo cientfico ytcnico, pensado como una plataforma de computo al tiempoque es un poderoso lenguaje de programacin de alto nivel. Sucreacin ha sido pensada en automatizar clculos y realizartareas matemticas complejas de manera interactiva,estructurada y programtica. por lo que su conocimiento bsicoderiva en una reduccin de tiempo en la realizacin de tareas deanlisis y visualizacin de datos, desarrollo de aplicacionessimples y publicacin de resultados.
